Note

Only one of the attributes @key, @name, and @ref may be used on any given instance of dataRef.

Neither a @restriction attribute nor a dataFacet child element may be used unless the dataRef refers to a datatype from the specification XML Schema Part 2: Datatypes Second Edition with a @name attribute.
